7y -63,,,,,,+xy-9x
\n" ); document.write( ".
\n" ); document.write( "7(y-9),,,,,+x(y-9)
\n" ); document.write( ".
\n" ); document.write( "(7+x)*( y-9),,,,,answer
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "often hard to visualize the last step,,,,starting at ab+cb = b(a+b),,,
\n" ); document.write( "let a=7,,,b= (y-9),,,c=x,,,,,,,7(y-9) + x(y-9) = (y-9)(7+x)
